Any info will help Thanx. 2012 si sedan.
Hmm. Maybe I should get Vit FP deal instead of the Full Race exhaust.....damn it I want that exhaust.imagine if your a solider, will you run faster with combat boots & 40lbs back pack or a light weight sneakers & a 20lbs back pack ?
these are common sense & foundation of building a performance vehicle.
reduce rotational weight = less energy use to move the vehicle forward..
this is a video of a vit tune with skunk cai, axion catless 3" dp, 3" full race cat back with 18lbs wheels (blue car) racing a car with no tune with stock catalytic converter + fkx racing power packages (black car)..
both driver are on a cell phone, on the same gear to prevent any advantage..
